Convert bar to attopascal
Please provide values below to convert bar [bar] to attopascal [aPa], or Convert attopascal to bar.
1 bar = 1.0000e+23 aPa. To convert bar to attopascal, multiply the value by 1.0000e+23; to go the other way, divide by it (1 aPa = 1.0000e-23 bar). Both units measure pressure and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 bar = 1.0000e+23 aPa
- 1 aPa = 1.0000e-23 bar
- 10 bar = 1.0000e+24 aPa
- 100 bar = 1.0000e+25 aPa
How to Convert Bar to Attopascal
1 bar = 1e+23 aPa
Example: convert 15 bar to aPa:
15 bar = 15 × 1e+23 aPa = 1.5e+24 aPa

Bar
The bar is a unit of pressure equal to 100,000 pascals, roughly the atmospheric pressure at sea level.
History/Origin
The bar was introduced in 1909 by the British engineering community as a convenient unit for measuring pressure, especially in meteorology and engineering contexts.
Current Use
The bar is widely used in meteorology, engineering, and industrial applications to measure pressure, although the pascal is the SI base unit. It is also common in tire pressure measurements and other pressure-related fields.
Attopascal
The attopascal (aPa) is a unit of pressure equal to 10^-18 pascals, representing an extremely small pressure measurement.
History/Origin
The attopascal was introduced as part of the SI prefixes to denote very small quantities of pressure, but it is rarely used in practical applications due to its minuscule magnitude.
Current Use
The attopascal is primarily used in scientific research and theoretical contexts where extremely small pressure differences are relevant, although it remains largely a conceptual unit.
Frequently Asked Questions
What is 1 bar in attopascal?
1 bar (bar) = 1.0000e+23 attopascal (aPa).
How do you convert bar to attopascal?
Multiply the bar value by 1.0000e+23. For example, 25 bar × 1.0000e+23 = 2.5000e+24 aPa.
What is 10 bar in attopascal?
10 bar = 1.0000e+24 aPa.
Which unit is larger, the bar or the attopascal?
The bar is the larger unit: 1 bar = 1.0000e+23 aPa.
